When it comes to improving fertilizer application and utilization, growers are encouraged to focus on the 4Rs — the right source, right rate, right time, and right place. Former Manitoba Ag soil fertility specialist John Heard won’t argue with that strategy but he would also like farmers to think about the ‘4Ls’ — lift-off, leftover,… Read More

What’s the most economic rate of nitrogen for corn? Where is that line between feeding the crop the right amount of the yield-producing nutrient and wasting dollars on excess product? University of Guelph sustainable cropping systems professor Dr. Adrian Correndo says a lot of field trials and research brainpower has been invested in identifying an… Read More

Biologicals hold great promise for improving crop production. From increasing root activity, soil microbes, and nutrient availability to building plant resiliency to abiotic stresses — this emerging crop input segment is bursting with product choices. But for farmers, selecting which product and application is right for their acres can be a daunting and confusing task…. Read More

Sweat the details and practice, practice, practice. It may sound like gridiron football strategy but it will also make farmers winners in the battle to improve soil health, says North Dakota-based independent agronomist and crop consultant Lee Briese. When it comes to improving soil health there are plenty of fixes — from reducing tillage to… Read More

Leaf twisting, burning, cupping, or crinkling — those are just some of the signs that a crop may be suffering from herbicide injury. Why do herbicides cause crop injury? University of Guelph weed researcher Dr. Peter Sikkema says injury causes can be classified into seven basic categories. That list includes extreme weather, unique or variable… Read More

When it comes to herbicides, the power to kill weeds and protect crops rests with the active ingredient. But how products are formulated can determine whether an effective active can be a winner or a loser in the field. “Quite frankly, there are active ingredients out there that wouldn’t be a product if not for… Read More

Growers and agronomists typically focus on the ear leaf at flowering when tissue testing corn to determine nutrient needs. But is that still the best choice for determining the optimal nutrient prescription for the crop as it moves into the reproductive stages? Purdue University professor emeritus Dr. Tony Vyn believes the evolution of modern hybrids… Read More

As we kick off a new year, it’s crucial for farmers and agricultural professionals to take a moment to reflect, not just on the past 12 months, but on the years gone by. Preparing for this week’s Ontario Agricultural Conference, where I will be giving a keynote presentation on effective farm management, has prompted me… Read More

Glyphosate-resistant Canada fleabane was first confirmed in Ontario in 2010. Fast-forward thirteen years and the weed now has developed resistance to multiple herbicide groups and can be found in Essex County, bordering Michigan, all the way east to Glengarry County, adjacent to the Quebec border. University of Guelph weed scientist Dr. Peter Sikkema has been… Read More

Tar spot has been spreading across North American corn growing regions ever since the leaf disease was first detected in 2015. Characterized by tar-like speckling on the upper surface of corn leaves, the fungal pathogen can deliver yield hits ranging from 20 to 60 bushels per acre (in highly infected fields). On this episode of… Read More

Variety choice and planting dates are two key factors that drive soybean yield. On this episode of RealAgriculture’s Soybean School, host Bernard Tobin asks whether later-maturing soy varieties are required for the highest yields and whether growers should plant soybeans before corn. For some answers, Tobin is joined by Michigan State University soybean educator Mike… Read More

Waterhemp that’s resistant to multiple herbicide groups continues to march across Ontario, but growers still have options to control the weed. There’s also emerging proof that integrated management could help growers take the fight to the spreading yield robber, says University of Guelph weed scientist Dr. Peter Sikkema. At the Ontario Agricultural Conference earlier this… Read More
